Disruptive Strategies for Removing Drug Discovery Bottlenecks

Drug Discovery is shifting focus from the industry to outside partners and in the process creating new bottlenecks, suggesting the need for a more disruptive overhaul. Technologies like high throughput screening (HTS) have moved to a larger number of academic and institutional laboratories in the US, with little apparent coordination or consideration of the outputs and creating a translational gap. While there have been collaborative public private partnerships in Europe to share pharmaceutical data, the USA has lagged behind. Sharing precompetitive computational models may be the next frontier to provide more confidence in the quality of the leads produced and attract investment. We suggest there needs to be an awareness of what research is going on in the screening centers, more collaboration and coordination. These efforts will shift the focus to finding the best researchers to fund and require a rethink of how to reward their collaborative efforts

Connecting knowledge to power: the future of digital democracy in the UK

Since its invention, the internet has been considered a ‘game-changer’ when it comes to democracy, with a worldwide network providing the potential to create a truly participatory democracy. This has yet to happen, but numerous individuals and groups are beginning to ask what can be done to marry the internet with representative democracy, including the Speaker of the House of Commons. Here, Chris Waller and Louis Reynolds discuss an exciting new project which seeks to use a wiki approach to crowdsource a submission to the Speaker’s Commission on Digital Democracy

New South Wales Vegetation classification and Assessment: Part 3, plant communities of the NSW Brigalow Belt South, Nandewar and west New England Bioregions and update of NSW Western Plains and South-western Slopes plant communities, Version 3 of the NSWVCA database

This fourth paper in the NSW Vegetation Classification and Assessment series covers the Brigalow Belt South-/1(BBS) and Nandewar (NAN) Bioregions and the western half of the New England Bioregion (NET), an area of 9.3 million hectares being 11.6% of NSW. It completes the NSWVCA coverage for the Border Rivers-Gwydir and Namoi CMA areas and records plant communities in the Central West and Hunter–Central Rivers CMA areas. In total, 585 plant communities are now classified in the NSWVCA covering 11.5 of the 18 Bioregions in NSW (78% of the State). Of these 226 communities are in the NSW Western Plains and 416 are in the NSW Western Slopes. 315 plant communities are classified in the BBS, NAN and west-NET Bioregions including 267 new descriptions since Version 2 was published in 2008. Descriptions of the 315 communities are provided in a 919 page report on the DVD accompanying this paper along with updated reports on other inland NSW bioregions and nine Catchment Management Authority areas fully or partly classified in the NSWVCA to date. A read-only version of Version 3 of the NSWVCA database is on the DVD for use on personal computers. A feature of the BBS and NAN Bioregions is the array of ironbark and bloodwood Eucalyptusdominated shrubby woodlands on sandstone and acid volcanic substrates extending from Dubbo to Queensland. This includes iconic natural areas such as Warrumbungle and Mount Kaputar National Parks and the 500,000 ha Pilliga Scrub forests. Large expanses of basalt-derived soils support grassy box woodland and native grasslands including those on the Liverpool Plains; near Moree; and around Inverell, most of which are cleared and threatened. Wetlands occur on sodic soils near Yetman and in large clay gilgais in the Pilliga region. Sedgelands are rare but occupy impeded creeks. Aeolian lunettes occur at Narran Lake and near Gilgandra. Areas of deep sand contain Allocasuarina, eucalypt mallee and Melaleuca uncinata heath. Tall grassy or ferny open forests occur on mountain ranges above 1000m elevation in the New England Bioregion and on the Liverpool Range while grassy box woodlands occupy lower elevations with lower rainfall and higher temperatures. The vegetation classification and assessment is based on over 100 published and unpublished vegetation surveys and map unit descriptions, expert advice, extra plot sampling and data analysis and over 25 000 km of road traverse with field checking at 805 sites. Key sources of data included floristic analyses produced in western regional forest assessments in the BBS and NAN Bioregions, floristic analyses in over 60 surveys of conservation reserves and analysis of plot data in the western NET Bioregion and covering parts of the Namoi and Border Rivers- Gwydir CMA areas. Approximately 60% of the woody native vegetation in the study area has been cleared resulting in large areas of “derived” native grasslands. As of June 2010, 7% of the area was in 136 protected areas and 127 of the 315 plant communities were assessed to be adequately protected in reserves. Using the NSWVCA database threat criteria, 15 plant communities were assessed as being Critically Endangered, 59 Endangered, 60 Vulnerable, 99 Near Threatened and 82 Least Concern. 61 of these communities are assessed as part of NSW or Commonwealth-listed Threatened Ecological Communities. Current threats include expanding dryland and irrigated cropping on alluvial plains, floodplains and gently undulating topography at lower elevations; over-grazing of steep hills; altered water tables and flooding regimes; localized mining; and the spread of exotic species, notably Coolatai Grass (Hyparrhenia hirta)

Lunar preform manufacturing

A design for a machine to produce hollow, continuous fiber reinforced composite rods of lunar glass and a liquid crystalline matrix using the pultrusion process is presented. The glass fiber will be produced from the lunar surface, with the machine and matrix being transported to the moon. The process is adaptable to the low gravity and near-vacuum environment of the moon through the use of a thermoplastic matrix in fiber form as it enters the pultrusion process. With a power consumption of 5k W, the proposed machine will run continuously, unmanned in fourteen day cycles, matching the length of moon days. A number of dies could be included that would allow the machine to produce rods of varying diameter, I-beams, angles, and other structural members. These members could then be used for construction on the lunar surface or transported for use in orbit. The benefits of this proposal are in the savings in weight of the cargo each lunar mission would carry. The supply of glass on the moon is effectively endless, so enough rods would have to be produced to justify its transportation, operation, and capital cost. This should not be difficult as weight on lunar mission is at a premium

PCBs and dioxins/furans in attic dust collected near former PCB production and secondary copper facilities in Sauget, IL

AbstractSamples of settled attic dust from fourteen buildings located within two miles of the Solutia W.G. Krummrich and Cerro Flow Products facilities in Sauget, Illinois were analyzed for PCBs and dioxins/furans using HRGC/HRMS. The facilities released vast quantities of PCBs and dioxins/furans into the environment over many decades. The concentrations and homologues present in the samples of attic dust and in samples of soil collected by U.S. EPA demonstrate atmospheric transport of PCBs and dioxins/furans from these manufacturing sites and local dumps contaminated with these pollutants. The results demonstrate that attic dust is a useful metric for assessing historical exposure to atmospheric emissions
